Touching Spaces: Interactive Physicalization for Exploring Spatial Information

Digital resources associated with socially significant public buildings and heritage sites range from basic information (e.g., names, functions, room numbers) to extensive archives, including images, oral histories, and videos—typically accessed through websites, mobile apps, or AR/VR platforms. However, these screen-based interfaces lack the tactile and spatial benefits of physical models. Physicalization supports embodied engagement, but physical models alone cannot convey the depth of digital records. This research explores hybrid physical– digital interfaces that link tangible models with digital resources to foster deeper engagement with physical settings. Our prototype integrates 3D printing, conductive paint, and touch sensors with a web service that links hotspots on a model to associated geometry, narration, and video displayed on large screens or mobile devices.We deployed the system in an exhibition at the University of Calgary and conducted a user study. Empirical findings indicate that participants considered the design easy to use and engaging, and that hybrid interaction enhanced both access to digital information and perceived understanding of each location’s history.
